Decoupled-DFIG fault ride-through strategy for enhanced stability performance during grid faults
Electric energy sector growth requires considerable investment in sustainable generation. Infrastructure must accommodate diverse and renewable energy sources, including DFIG technology, which poses problems for system stability. This paper proposes a new method which prevents unnecessary disconnection of DFIG wind turbines during system faults thereby minimising impact on stability and reducing CO2 emission. The work benefits a power system operator by ensuring stability throughout grid disturbances. Additional Science Foundation Ireland (SFI: 06/CP/E002) funding was leveraged in 2011 to continue this work which promoted greater collaboration with B9 (wind operator) and SONI (NI system operator) to validate academic research and system integration.
